To all whom it may concern:

Be it known that we, Anon J. Gmnesne and BERNARD FIELD, both citizens of the United States, and residents, respectively, of the city, county, and State of New York and the city and county of Plymouth, Massachusetts, have invented a new and useful rocess of Treating Organic Matter for Fertilizer Purposes, whereby its value as a fertilizer is greatly enhanced, because it, is more quickly available, and therefore serves its purpose when applied to trees or other vegetation in a. markedly-increased degree.

It is a fact that the constituents of a soil should be available for vegetation growth at the time when such growth would naturally be most active; and that unless they are thus available, the 'aluable substances of which such constituents are composed or into which they may be transformed, fail torender the full benefit of which they are capable. This is true not onl of the natural constituents of the soil, but of added constituents as well.

If treated by our process, organic matter, which otherwise would not yield its constituents to vegetation at all, or if at all, would yield them so slowly as to be not available in quantity to the vegetation at the time when they would be of the greatest value,- namely, when the tendency to grow is greatestis modified so that it may be applied, and will readily yield its constituents to the vegetation at the said time when they can best be utilized to obtain the greatest effeet.

In addition, difierent soils vary in their ability to transforn'i organic matter so as to render it available for vegetation growth. Organic matter treated by our process is made available for plant growth without being entirely dependent upon the soil in which it is applied to the vegetation.

In our process we use a sponge or leavening mass, which may be prepared in a number of ways, a preferred form of which is as follows:

To one-half barrel of bran and sawdust in equal amounts by volume, we add three times by volume of water, one pound of corn starch and six ounces of carbonate of ammonium. This is thoroughly stirred and at Specification of Letters Iatent.

'dred pounds of powdered potash Patented June d, rats.

Application filed April 27, 1917. Serial No.16,958.

the same time an infusion of acid producing bacteria, such as Bacillus cold, Bacillus mdguzfus or the like is added.

This mixture we allow to stand from twenty-four to' forty-eight hours when an active growth of the bacteria will be present. At this stage the sponge may be added to and thoroughly mixed with a ton of the organic matter to be treated. liumus may be used for this purpose and if its already strongly acid, a quantity or powdered limestone is added prior to mixing with the sponge. 'lhe-n we add one hundred pouiuls of powdered phosphate slag and one hunfeldspar.

This mixture is allowed to work for several days, after which it may be applied at once to the vegetation to be treated; or if it is intended for future use it may be dried either by exposure to the air or in a suitable drying apparatus at a low temperature. I

It the mixture is so dried, water may be added immediately before or shortly after it is subsequently applied to the vegetation to be treated.
